Top 10 Air Conditioning Mistakes To Avoid


Although commonly taken for granted, the air conditioner is one of the essential appliances in the house. Without the air conditioner, the home wouldn’t be comfortable during hot summer days and the coldest of winter days. Having the right sized air conditioner, and ensuring it is installed correctly is the first step to enjoying some comfort in the house. While it may seem simple, air conditioning machines are complex hence should be handled with care to avoid running into problems, as well as ensure they function correctly. Even the slightest mistake with the AC system can have its consequences. Outlined below are 10 of the most common AC mistakes and how to avoid them from

  1. Investing in An Improperly-Sized AC System

Although unknown to many, investing in the wrong-sized air conditioner will always come at a cost. For instance, bigger AC systems than necessary will only use up lots of power and even cause sharp temperature changes. A smaller unit is even worse as it will only break down quickly. Having an HVAC expert help you choose the right-sized system for your house, and applications would be a wise idea.

  1. Incorrect Positioning of the AC

An incorrectly installed or positioned AC unit reduces its efficiency while increasing energy consumption. It is for this reason you should pick just the perfect spot to place both the outdoor and indoor unit. The outdoor unit should be placed away from direct sunlight or in a shaded area for the best performance and efficiency. Window-mounted systems should be installed while tilted to ensure proper drainage. In addition to this, the thermostat needs to be installed/positioned in a neutral area to ensure it controls the air conditioner correctly for the best results.

  1. Wrong Thermostat Settings

The thermostat can be termed as the brain of the AC system. Incorrect settings can cause the entire system to produce false results. Setting the thermostat too low will only lead to a colder room while setting it too high will strain it hence higher energy bills. Setting the thermostat right however eliminates the risk of straining it too much, and ensuring your home is comfortable enough.

  1. Ignoring the Air Filters

Air filters are an integral part of the AC system. These help filter out allergens, dirt, and other foreign materials from getting into the system and the house in general. Without these filters, the air quality inside the home would be greatly hampered, and especially if it is dusty outdoors. Neglecting these filters causes dust, grime, and debris buildup which makes the fans to work a little harder to keep the air flowing. Replacing the air filters at least twice per year can help prevent such situations.

  1. Failure to Service/Clean Coils and Fins

Replacing the air filter isn’t enough to ensure the AC system functions properly. The evaporator coils and fins are dust and grime magnets hence should be kept clean at all times. Neglecting these fins only leaves layers of grime and dust which makes it hard for the evaporator to work efficiently. This again decreases the entire unit’s efficiency while increasing power consumption.  Taking some time to clean these fins and coils however improves the efficiency of the system. Consider doing this just before the warm season starts or after a storm.

  1. Leaving the AC ON When No One Is Home

Most people will intentionally leave their AC systems ON when going out. Although the idea might be to ensure the house is comfortable when you step back, leaving the AC on for hours only wastes energy. Instead of leaving the AC on, why not invest in a smart thermostat. A programmable thermostat should turn down the AC when no one is home, and back ON again when you are about to come back. Smart thermostats can help save lots of energy and even increase the efficiency of the system in the long run.

  1. Avoiding a Replacement

Most people will cling on the old AC system for eons in the name of saving money for replacement units. Although the 10-year old AC system might seem to be running just ‘fine,’ chances are it is using up more power than it should, or its efficiency has declined significantly. Old systems will not only perform adequately when compared to newer ones but also cost more money in repairs and servicing. If you have been using your system for more than ten years, it might then be time to consider a replacement. Newer systems run efficiently and are bundled with useful features older systems don’t have.

  1. Postponing Routine Maintenance

An Air Conditioner can run for months without needing any serious maintenance or servicing. This however doesn’t mean you should delay the next routine maintenance just because it seems to be running properly. The main idea behind routine maintenance is to diagnose potential issues, as well as make calibration adjustments to ensure the system runs efficiently. Most minor issues will be sorted out during the routine maintenance, and cost a lot less as compared to fixing an already broken system.

  1. Leaving the Windows Open

Leaving the windows open (in hot weather) allows hot air in making the house warmer than it should. This forces the AC system to work harder in the attempt to keep temperatures low. Keeping the windows closed, and drawing curtains and drapes reduces the pressure on the AC system, hence the best thing to do. Straining the AC system only attracts higher energy bills at the end of the month.

  1. Neglecting the Drain

Air conditioning systems use drains to remove condensate moisture from the unit and away from the house. The drain is one of the most forgotten parts in the air conditioner that if clogged, can affect the AC’s performance, efficiency, and even damage surrounding walls and the floor.

These are just but several of the various air conditioning mistakes most people make. Avoiding these mistakes and working with a certified HVAC contractor should see you enjoy the comfort of your home. Fixing most of these issues should also give your HVAC system a longer lifespan, reduced power bills, as well as get value for your money. Be sure to invest in the right-sized AC system, and schedule regular servicing and maintenance for the best results.
